SMT processing cost analysis and how to select a good SMT processing plant?

1、 Workshop and environment

The dust-free workshop is about 310 square meters, with central air conditioning. The workshop has been decorated, so you do not need to bear the decoration cost, but you need to connect electricity and gas.

2、 Production line distribution

1. Four automatic patch production lines are planned for the whole workshop.

2. In the first phase, an automatic production line is put into operation, which is mainly used to process the lamp strip of LCD module backlight and FPC soft board patch manufacturing.

3. In the future, the production line will be increased in due time according to the output of customers and the needs of customers in other markets.

4. The production line is equipped with two mobile phones.

3、 Machine configuration

1. The first automatic production line configuration.

2. Loading machine+automatic printing machine+docking station+high-speed paster+docking station+high-speed paster+docking station+reflow soldering furnace (eight temperature zones)+2m workbench.

4、 Phase I funds

The machine configuration in 1.3 is about 400000 yuan.

2. About 20000 processing jigs and auxiliary facilities.

3. The working capital (mainly referring to staff salaries) of the first three months is to be determined, estimated to be less than 60000 yuan.

4. The first phase of direct investment must be controlled within 500000 yuan.

5、 Cost analysis (month as unit)

1. Take the first production line as an example to analyze the production costs and expenses when the full month capacity is saturated.

2. Rent: When there are only two production lines, the rent is not required to be paid. When there are more than three production lines, the rent will be discussed separately.

3. The actual monthly cost shall be controlled within 50000 yuan.

6、 Income analysis

If it is calculated by one production line. How much is the monthly revenue of all-around manufacturing? If the average production capacity is 80%, what is the profit?

7、 Add the second and third production lines

According to the relatively stable processing orders of target customers or newly developed customers, consider adding the second and third production lines. With the increase of production lines, the average cost will decrease and the yield will increase accordingly.

8、 Failure cost (risk)

What are the factors that will lead to the decrease of the income of this project? What is the amount of loss if the economic benefit decreases in half a year? (Open question, you can assume certain conditions)

How to select a good SMT processing plant?

Smt processing plant

1. Concept of Cooperation

SMT processing is a part of the whole process of electronic products. If the machinery and equipment are highly developed and the management is perfect, the professional cooperation level of the SMT processing factory will determine whether your PCBA boards can be delivered on time, whether the quality can be controlled, and whether they can be repaired immediately. This added value can be expressed in terms of the unit price difference between 8cm and 9cm. How to investigate the coordination degree of the SMT processing factory on the spot? Start with people. Through talking with the management and even the boss of SMT processing plant, observe whether they have a sincere attitude and faith in dealing with people. In addition, you can also learn about the reputation of the processing plant and the customer cases served by the third party.

2. Quality Control

In order to reduce the unit price, many SMT processing plants fight in the market at the risk of sacrificing quality, reducing QC personnel or not providing AOI for testing. In the process of evaluating the SMT processing plant, it is necessary to observe and understand in detail whether the IQC, after furnace intermediate inspection, QC and other series of posts in the warehouse are set, whether the AOI testing equipment is reasonable, whether it is opened and used, and whether the engineering personnel introduce and document the quality management methods. Only by understanding in multiple aspects can you ensure that your products can be processed perfectly.

3. Spirit of management and employees (WorkPassion)

The mental outlook of front-line employees and managers determines whether your products can maintain a high yield and consistency, because SMT products are made by people or operating machines and equipment. Whether the communication with the manager is smooth and passionate, and whether the employees are meticulous and perform their duties.
